MMM' E 'IIN UNITED STATES PATENT @Fries9 JACOB DIMOND, OF PITTSFIEL'D,ILLINOIS.

FLOOD-GATE.

SPECIFICATION forming part of Letters Patent No. 370,769, dated October4, 1887.

Application filed April 4, 1887. Serial No. 233,613.

To all whom, it may concern:

Be it known that I, JACOB DIMOND, of Pitts` field, in the county of Pikeand State of Illinois, have invented certain new and useful Improvementsin Flood-Gates; and I do hereby declare the following to be a full.,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in gates, the object of the samebeing to construct a gate that will automatically close itself whenopened.

A further object is to construct a gate .that may be used as aflood-gate.

With these ends in view my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claim.

In the accompanying drawings, Figure l is a view in elevation of myimproved gate.

Fig 2 is a plan view of same. Fig. 3 is a vertical section.

A A represent the upright posts or standards to which the gates arehung.

B B represent the gates, hinged at b5 to the upright posts A A in anywell-known and approved manner.

C is a cross-beam connecting the upright posts and adapted to limit theinner move` ment of the gates and form a firm bearingsurface for saidgates when closed, as well as to strengthen the upright posts.

Secured near the top of each post A A', and projecting therefrom, are apair of arms, a b and a b', the former of which are slightly above andto one side of the other ones. These projecting arms are provided ontheir lower faces, near their free ends, with notches for the receptionof clips D. Said clips are preferably of metal, and have pulleys e3 c'and (362 journaled'therein.

Attached to the cross-beam O is an inwardlyprojecting beam or strip, E,having a box, F, secured to its free end, said box consisting of a blockof wood or metal having slots e cut in the ends thereof to permit of theintroduction (No model.)

of Vpulleys G, which latter rotate upon axles or pins running verticallythrough said box, and secured against vertical displacement by nuts orrivets.

Cords or chains H, secured to the top rails of the gates, pass round thepulleys G, and are strung around the lower set of pulleys, e' e2, in thearms b b', which are set nearer the gates than are the other set ofarms, a a. From there they are strung around the other set of pulleys,e3 et, after which a Weight, K, is attached to the free end for thepurpose of closing the gate when opened.

There will be seen at a glance the superiority possessed by myimprovement, inasmuch as it can be used as a dood-gate with muchfacility, and it is adapted to be used where a superior farm-gate isrequired. When used as a nood-gate, slight changes, which only relate tothe material used, are resorted to. For in stance, the gates arepreferably made of metal, and the cords connecting the same with theweight are made of chains or wire rope, While a box or other suitablereceptacle filled with stones or other weighty articles might besubstituted for regular weights. When spanning a stream, the pressure ofwater or obstructions against the gates forces them open, allowing theobstruction to pass, when, should the water subside, thus removing thepressure on the gates, the latter automatically close, resuming theirnormal position.

It is evident that slight `changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention. For instance, the gates may be so hungthat only one may be operated from a side. Such a construction isespecially applicable to railroad stations where there is constantly acrowd going and coming,thus obviating crowding and jamming.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-V The combination, with l the posts, gateshinged thereto and a cross-beam secured ben tween the posts,agninstwhieh'the gates abut In testimony whereof I have signed this whenclosed, of arms secured on each post, specification in thepresenee oftwo subscribing each arm having a depending clip with a pul- Witnesses.

ley journaled therein, a projecting beam se- 5 cured to the cross-beamand havin(r a pair of Ilm pulleys, and exible connections stlung aboutJACOBm/KDIMONB the pulleys and having connection with it gate at one endand with a Weight at the Witnesses:

other, for the purpose substantially as set C. W'. PATTERSON, ro forth.F. P. WACKERMAN.
